Uncanny X-Men, Vol. 1 #200 (1985)

The Trial Of Magneto!
Magneto has voluntarily put himself on trial in the world court. The defense argues successfully to restrict the charges to those following his transformation into an infant at the hands of Mutant Alpha in Defenders #15 and 16. When Fenris attacks the proceedings and Magneto acts to protect the innocent, things start to look promising. Unfortunately, the situation is dire once more when the Professor's injuries finally catch up with him.
